Corrugated board structure

ABSTRACT

A corrugated board includes a first board part, and a second board part; the second board part has several propping plates on one side thereof; the first board part is securely joined to the propping plates of the second board part with a space existing between the first and the second board parts so as to allow heat dissipation by convection in the corrugated board.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a corrugated board, more particularlyone, which is made of aluminum, environmentally friendly, and fast toprocess and manufacture, and has a relatively good heat-dissipationcapability.

2. Brief Description of the Prior Art

Metallic corrugated boards are used as major materials for constructinggarages, warehouses, provisional houses, and houses for special purposesby people in tropical/subtropical countries, which are usually situatedin alfresco places and vacant lands such as courtyards and tops ofbuildings to help to block direct sunlight. Such corrugated boards areinexpensive, and are joined together by means of screws. Therefore, suchhouses can be rapidly and easily assembled and disassembled, and ittakes relatively little time and expense to construct such a house.Consequently, houses comprising such metallic corrugated boards aregetting more popular.

Shown in FIG. 4 is a common metallic corrugated board to be used as amaterial for iron sheet houses such as provisional houses, and housesfor special purposes. The metallic corrugated board comprises severalspaced raised portions, and depression portions intervening between theraised portions, and is acid-washed, and electroplated with tin so asnot to rust. Furthermore, after the corrugated board is electroplatedwith tin, it is spray-painted and roasted to be more pleasant-lookingand still less likely to rust.

However, the above metallic corrugated board has the followingdrawbacks:

1. The manufacturing method for the corrugated board includes theacid-washing step, and the spray-painting and roasting, which willproduce much pollution, being not acceptable in terms of environmentalprotection.

2. The tin plating and the paint over the corrugated board will producepollution when the corrugated board is discarded.

SUMMARY OF THE INVENTION

It is a main object of the present invention to provide an improvementon a corrugated board structure to overcome the above problems.

A corrugated board structure according to an embodiment of the presentinvention includes a first board part, and a second board part. Thesecond board part has several extension plates thereon, and severalpropping plates perpendicular and joined to the extension plates. Theextension plates each have several through holes thereon. The secondboard part is securely joined to the first board part at the proppingplates thereof such that a space comes into existence between the firstand the second board parts to allow heat dissipation by convection inthe corrugated board.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be better understood by referring to theaccompanying drawings, wherein:

FIG. 1 is an exploded perspective view of the corrugated board of thepresent invention,

FIG. 2 is a perspective view of the present invention,

FIG. 3 is a sectional view of the present invention, and

FIG. 4 is a perspective view of the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a preferred embodiment of a corrugated boardstructure includes a first board part 1, and a second board part 2, bothof which are made of aluminum. The manufacturing and processing methodof the board parts 1 and 2 doesn't include acid-washing, electroplatingor spray-painting and roasting. Therefore, it causes less harm, andtakes relatively little time to manufacture and process the corrugatedboard of the present invention.

The first board part 1 has several raised portions 11, and depressionportions 12, which are evenly spaced, and intervene between the raisedportions 11. The depression portions 12 have several screw holes 13thereon.

The second board part 2 has several raised portions 21, and depressionportions 22, which are evenly spaced, and intervene between the raisedportions 21. The raised portions 21 of the second board part 2 each havean extension plate 23 sticking outwards therefrom. The extension plates23 each have several through holes 231 thereon. The extension plates 23each have a propping plate 24 secured on a free end thereof such thatthe extension plates 23 are perpendicular to the propping plates 24. Thepropping plates 24 have screw holes 25 thereon.

In assembly, referring to FIG. 1 to FIG. 3, the first board part 1 ispropped on the propping plates 24 of the second board part 2 at thedepression portions 12 with the screw holes 13 being each faced with acorresponding said screw hole 25. And, threaded fixing elements 3 arepassed through the screw holes 13 and 25 so as to secure the first andthe second board parts 1 and 2 together; thus, a space 4 exists betweenthe first and the second board parts 1 and 2 to allow heat dissipationof the corrugated board by convection. In addition, existence of thethrough holes 231 on the extension plates 23 of the second board part 2can increase airflow in the space 4 so as to enhance theheat-dissipating capability of the first and the second board parts 1and 2.

From the above description, it can be seen that the present inventionhas the following advantages over the prior art:

1. Both of the first and the second board parts of the present inventionare made of aluminum, and manufactured and processed according to amethod that doesn't include acid-washing, electroplating orspray-painting and roasting. Therefore, the manufacturing and processingtake relatively little time, and the corrugated board of the presentinvention has a relatively good heat-dissipation capability.

2. A space is provided between the first and the second board partstherefore heat dissipation by convection is allowed in the corrugatedboard.

3. Through holes are provided on the extension plates of the secondboard part. Therefore, airflow increases in the space between the firstand the second board parts, and heat dissipation capability thecorrugated board of the present invention is enhanced.
